These results are consistent with other C budget analyses in
Wisconsin, USA (White et al., 2005) and in Finland (Liski
et al., 2001) that have incorporated components of silviculturally
associated C emissions. The work in Wisconsin only
incorporated C emissions from the use of harvesting equipment
and found 0.08–0.09 Mg C emission per Mg C harvested. This
extrapolates to approximately 2 Mg ha1 of C emissions. The
work concludes that at the forest management boundary
managed forests are net sinks of C. The work in Finland
specifically focused on how a 60-, 90-, or 120-year rotation
length would impact net C stocks over a 300-year simulation.
The results of this analysis generally indicated that longer
rotations would increase the stored C stock (partly as wood-inuse)
and would reduce C emissions from harvesting and
processing operations per unit of wood harvested. The more
complete accounting of all silvicultural C emissions in the
current study also supports the value of harvesting larger trees
and utilizing silviculture to accelerate tree growth to a saw
timber (or chip-n-saw) class.
